Our range of off-the-shelf Chilltek insulated shipping envelopes and mailers are designed to suit your needs for smaller deliveries that don’t require an insulated shipping box.
The robust exterior of our insulated mailers is manufactured from puncture resistant fully recyclable LDPE whilst the interior pocket is created using low-density polyethylene to keep total shipping weight down.
Envelopes have a 70mm flap and 20mm maxi strength tamper proof sealing strip.
